Worldphones That Work On Both Verizon And AT&T In The United States

[Jim1648]

I haven't paid much attention in the past to worldphones because I am not exactly a globetrotter. However, are there any worldphones that will work on both Verizon and AT&T here in the United States? I have read that the newest Verizon iPhone 5 will, but I am interested in finding out if, for example, there are any Motorola Androids that will work on both Verizon and AT&T.
